Flex :: Manually Setting Max And Min On A VerticalAxis?
Oct 6, 2009
I have a candlestick chart that is working great when the numbers being dealt with are large but when the numbers are small the vertical axis starts at the very top of my data and ends at the very bottom. For example if my max number in my XML is 12 and my min is 11 the charts top is 12 and the charts bottom is 11 with 11.2, 11.4, 11.6, 11.8 in between. How can I force the chart to do 22 to 1 on the vertical axis ({maxgraph+10} and {mingraph-10}).

Hi everyone. This should be a simple question. Using flash professional CS5
I'm manually setting up stuff on the stage (authortime). And i've placed an object at a specific rotation. I now want to place another object, with the exact same rotation.
The problem is, i cannot find any way to read the object's rotation, or to specifically set it (ie: by typing in a value, rather than by manipulating editor handles)
I'm looking in the properties window and there's readouts/settings for position, size, scale, a ton of 3D properties, color effect properties, display properties, and filters. But there's no field for rotation. why the hell not! Isn't that a ridiculously simple and stupid omission?
so far the best method i can find is using free transform, and adjusting it manually til it "looks right", which is a very un-exact way of doing things.

I'm stuck thinking about the best way to go about setting a line segment's position, I have a class Line(length, angle, previous) being called from a class Polygon. Right now I have:
public class Line extends Sprite {
public function Line(length:Number, angle:Number, previous:Line = null) {
if (previous != null) {
this.x = previous.end.x;

I have two columns: the left one is a Canvas containing an mx:Tree and the right one is a Canvas containing a Canvas (to allow for scrolling) of some custom Sprites that go along with the tree nodes on the left. I made the right Canvas scrollable (horizontal and vertical) and I want the vertical scroll to also scroll the left Canvas so that the tree nodes line up with their representations on the right. The scrolling portion works fine and when I embed with wmode="window" there are no problems. Unfortunately, the customer requires dynamic HTML to overlap the Flash at times and when using wmode="opaque" or "transparent", there are issues. The scrolling still works, per se, but Flash does not seem to redraw either Canvas appropriately. The Canvases become out of sync and artifacts often remain on the right side.I catch a scroll event on the right column and update the scroll position on the left column like so:
public function onTimelineScroll(scrollEvent:ScrollEvent):void {
leftColumn.verticalScrollPosition = rightColumn.verticalScrollPosition;
}

I need to trigger the hover state of a Flex button programatically, so that it looks like the user is hovering over it. There is a flex page about "Manually dispatching events":
[URL]
Which would work, but what I'd really like to do is change the style of the button without having to throw an event. How can I do this?

I have a standard combobox that dispatches a collection event when the dataprovider finishes initializing:
my_cb.addEventListener( CollectionEvent.COLLECTION_CHANGE, getMyStuff );
Then I have a custom component that also has a dataProvider. How do I get it to dispatch a collection change event when its dataprovider finishes loading?From what I've read, I can't do it. Will dispatching a propertychangeevent work?
UPDATE:I have a custom component that I call 'SortingComboBox' but it is not a ComboBox at all; it extends Button and I set is dataProvider property to my arraycollection, model.product (which is an arraycollection). how I use the dataProvider in that component:
code
[Bindable]
private var _dataProvider : Object;
public function get dataProvider() : Object
{[code]..........
In the createChildren() method of this component, I use this:
BindingUtils.bindProperty(dropDown, "dataProvider", this, "dataProvider");
The dropDown is a custom VBox that I use to display labels.

I'm trying to consume a .Net web service of mine in a Flex Builder 3 project. The function's signature in the service is:
bool MyFunction(Enums.Channels var1, Enums.Payments.PayMethods var2)
I tried importing the WSDL with the wizard but when I tried to call the web service it results in an error stating
"Cannot marshall type "http://www.w3.org/2001/XMLSchema::EnumsChannel"to simple type"
What kind of object do I need to create in Flex Builder 3 to pass into the webservice so that it will recognize it as the appropriate type? The wizard is not correctly creating the appropriate type. Here is the xsd for the enums.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://schemas.datacontract.org/2004/07/My.Shared" elementFormDefault="qualified" targetNamespace="http://schemas.datacontract.org/2004/07/My.Shared">
<xs:simpleType name="Enums.Channels">[code]....
I'd like to try to build my own objects to call the service myself (without the wizard).... created the mx:WebService and mx:Operation but not sure how to handle the enum parameters.

Whenever you resize a datagrid by hand (not via code), the last column seems to retain most of the width. What's worse, whenever you extend it and shrink it to a large degree, the other columns can get smushed. Here's a perfect example: The ideal solution would distribute width equally or in proportion to the length of the text. In addition, if would avoid covering text when it's not necessary. Now, setting the width to 0.5 in the example above does seem to alleviate the issue, but not prevent it entirely. What I'd also like to know if there are any well polished, custom datagrids out there that solve this. From trying to find a solution, I suspect the only solutions available are more ad-hoc.

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.

How do I limit my amf sessions to flex over pyamf?
I have set up a pyamf gateway to that serves value objects that originate from a django admin panel, through sqlalchemy to my authenticated flex client. It's working great, however there is a problem. My sessions are persisting and clogging up the server, so after about 20 or so AMF sessions are authenticated, it refuses any more until I restart the server.

I'm making a trivia in an Air application, a question, three buttons, after you choose one, the right button gets coloured green, the wrong ones get coloured red. I was trying to do this changing the styles, so I created a Button.Right and a Button.Wrong style, but I also need to disable the buttons so they don't get clicked more than once while I'm showing the correct answers.
So I'm having trouble making it so the buttons don't look greyish and with the alpha turned down when I set their enabled property to false. I'm trying to be as minimalistic as possible here, changing disabled-overlay-alpha or disabledOverlayAlpha in the css file doesn't seem to do the trick, neither does changing disabledBorderColor

For example:
sampleComponent.explicitMinWidth = 500;
sampleComponent.explicitWidth = 10;
Sets the width of the sampleComponent to 10, even though I've set the minimum width to 500.The same thing seems to happen with width. In Adobe's documentation, it states that 'measuredMinWidth - Specifies the default minimum height and minimum width of the component, in pixels. Flex cannot set the size of a component smaller than its specified minimum size.I've tried setting the measuredMinWidth as well, same result.Eventually, I tried every combination of minimum width settings I could, but they were all ignored when I set the width (or explicit width).
sampleComponent.measuredMinWidth = 300;
sampleComponent.minWidth = 300;
sampleComponent.explicitMinWidth = 300;
sampleComponent.width = 10;
Additionally, what is the difference between width and explicitWidth, in every case I've tried, they have performed identically (couldn't find any help on this either)

We recently built a new dev server for flex builder and installed coldfusion 8. We currently have everything working on our old server using coldfusion 7. We copied the services-config.xml and our project over to the new server. It compiled fine, I updated all references to the new server. When I try to run the flex application I receive the following error:
Warning: Failed to load policy file from http://localhost/crossdomain.xml
* Security Sandbox Violation *
Connection to http://localhost/flex2gateway/ halted - not permitted from file://ourServer/folder/ourProject/bin-debug/ourProject.swf
We created a valid crossdomain.xml file on the localhost (which I wouldnt think would be necessary since everything is on the same server)

I have a VBox that I am populating programatically, After a particular event (dragDrop) I do some calculations, reorder some variables, then re-build the VBox. This all works great, but I want the VBox to scroll back to the correct verticalScrollPosition. I tried even the simplest thing: myVBox.verticalScrollPosition = 200But I just can't get it to set the scroll position after it's rebuilt.
Edit: per Franky's response I realized that my dragDrop function was calling the rebuilder function then the position setter function back to back, which means it wasn't done being built when it was trying to set. Now I'm passing the position I want the box set to to the rebuilder function which sets the scroll position at the end of building the VBox and everything works out great.

I'm setting up a functional test suite for an application that loads an external configuration file. Right now, I'm using flexunit's addAsync function to load it and then again to test if the contents point to services that exist and can be accessed.
The trouble with this is that having this kind of two (or more) stage method means that I'm running all of my tests in the context of one test with dozens of asserts, which seems like a kind of degenerate way to use the framework, and makes bugs harder to find. Is there a way to have something like an asynchronous setup? Is there another testing framework that handles this better?

I want to set value of a progress bar in an accordion but I am encountering 'setProgress is not a function' error. If I move the progress bar out of the Accordion then the error goes away and the progress bar appears fine. I want to set the progress bar eventually to {repMonitor.currentItem.threatLevel} but for now I am just testing with hypothetical threat value i.e 60

We bought this Flash template to save time:to make this siteI knew a template would limit us (especially since I only know HTML/a little CSS), but of course, we need a few tweeks. To save time (and if anyone is interested), I have uploaded the source files so you can see the structure here:The flash file is set up like this:Fla file for all the image souces & layoutIndex.html File has some sort of fancy javascriptText.html file is the editable file where non-flash-knowing dingbats like me can just edit the text and POOF! Magic!I know I have bastardized them from the original and some stuff is probably wonky.The biggest problem is that the "thumbnails" that you click on at the starpage are auto-generated, cropping the top left 100x100 square. I don't know why this is the case, and honestly, I think it looks awful.
Is there any way to manually set the thumbnail images, so they are cropped artistically rather than randomly? I asked the template tech support and they told me to "make my images 100x100". I did that for the first blue logo, and it looks like CRAP! Sure, I have the icon I would like, but when someone goes to browse the gallery, they get a 100x100 icon displaying instead of a lovely fullscreen pic.
